Therefore you need to change the NumPy’s seed at every epoch, for example by np.random.seed(initial_seed + epoch). Moreover, you won’t have these issues if you sample random numbers using PyTorch (for example, torch.randint) or Python’s built-in random number generator.
For details, see RandomState. Using np.random.seed(number) has been a best practice when using NumPy to create reproducible work. Setting the random seed means that your work is reproducible to others who use your code. But, now when you look at the Docs for np.random.seed, the description reads: This is a convenience, legacy function. The numpy.random.seed () function uses seed=None as the default value.
This is certainly what I'd expect, and likely follows the principle of least surprise: numpy random in a new process should act like numpy random in a new interpreter, it auto-seeds. Numpy.random.seed()用来设置随机数生成的随机种子。在seed(n)中，当n的值相同时，生成的随机数相同，其中的n为整数。 用例子说话： 首先引入numpy import numpy as np 设置随机种子，生成随机数 np.random.seed(0) np.random.rand(4) array([ 0.5488135 , 0.71518937, 0.60 Python Number seed() Method - Python number method seed() sets the integer starting value used in generating random numbers. Call this function before calling any other random module functio numpy. random 함수의 아웃풋은 여러분이 사용하고 있는 seed 값에 달린 것이다. 간단한 예를 통해 살펴보자. 첫 번째 예에서는 seed 값을 0 으로 설정했다.
As noted, numpy.random.seed(0) sets the random seed to 0, so the pseudo random numbers you get from random will start from the same point. This can be good for debuging in some cases. HOWEVER, after some reading, this seems to be the wrong way to go at …
Syntax. Following is the syntax for seed() method −.
As noted, numpy.random.seed(0) sets the random seed to 0, so the pseudo random numbers you get from random will start from the same point. This can be good for debuging in some cases. HOWEVER, after some reading, this seems to be the wrong way to go at it, if you have threads because it is not thread safe.
2019-05-06 · NumPy random seed is simply a function that sets the random seed of the NumPy pseudo-random number generator. It provides an essential input that enables NumPy to generate pseudo-random numbers for random processes. 2018-08-23 · numpy.random.seed. ¶. numpy.random.seed(seed=None) ¶.
See the NumPy documentation for numpy.random.seed . 7 Apr 2020 For instance one might use np.random.random without knowing that the seed of the global RNG was set somewhere else in the codebase. numpy.random. seed (seed=None)¶. Seed the generator.

The provided seed value will establish a new random seed for Python and NumPy, and will also (by default) disable hash randomization. 2021-04-09

This can be good for debuging in some cases.
If it is an integer it is used directly, if not it More Examples. The good news is that by carefully setting the random seed across your pipeline you can achieve reproducibility. The “seed” is a starting point for the sequence and the guarantee is that if you Therefore you need to change the NumPy’s seed at every epoch, for example by np.random.seed(initial_seed + epoch). Moreover, you won’t have these issues if you sample random numbers using PyTorch (for example, torch.randint) or Python’s built-in random number generator. This is a convenience, legacy function. The best practice is to not re seed a BitGenerator, rather to recreate a new one. This method is here for legacy reasons.
